IMPROVEMENT IN LAM P-BURNERS.

Specification forming part of Letters Patent No. 55,546, dated June 12, 1866.

To all whom it may concern:

Be it known that I, WILLARD H. SMITH, of the city of New York, in the State of New York, have invented a new and Improved Lamp- Burner and I do hereby declare that the following is afull, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective. Fig. 2 is a section. Figs. 3 and 4 are sections of the isolators. Fig. 5 is modification of the tip to the burner.

The nature of my invention consists in the construction of a cheap. and simple mode of isolation to prevent the heat of the flame from being conducted to the oil-reservoir.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation,reference being had to 'the accompanying drawings wherein the same letters represent corresponding parts.

The base of the burner is composed of two parts, A and B, fitting each other, filled with cork or its equivalent at O. D is a double wick-tube, which 1 do not claim. Around the outside tube is fitted a thin metal plate, (seen in Fig. 4,) with points or teeth on its edge, every alternate one of which is turned down and driven into the lower cork, and the others are turned up and driven into the upper cork so as to hold the pieces firmly together. The tube fits snugly into both these pieces of cork, but does not touch either the upper or lower metal. plate inclosing the cork, so the tube is entirely isolated from those parts that come into contact with the reservoir.

G is a sleeve fitting over the outside of the double wick-tube having bearing enough to hold it in place by friction. On this sleeve is secured a disk by which it is adjusted up or down to regulate the flame. To the top of this sleeve is secured a round cup-shaped tip, E, having air-holes cut through its sides throughout its entire circumference, to admit air to the flame. At F, Fig. 5, is shown a modification of the tip, oval in form, with air-holes only in the sides to produce a flat flame.

I do not claim the double wick-tube; nor do I claim cork or any other non-conductor but What I do claim, and desire to secure by Letters Patent, is-

l. The metal plate or its equivalent, with points between the two pieces of cork entering both as represented, as and for the purpose set forth.

2. The two parts A and B. constructed and combined as and for the purpose set forth.

3. The mode of fastening the wick-tube to the said metal plate and of fitting the same snugly in the said cork or other non-conductor, so as to hold the same flrmlyin its place without touching the metal plates inclosing the non-conductor either above orbelow, as set forth.

4. A combination of the parts A and B, filled with cork or other non-conductor, fastened together by means of the metal plate, as shown in Fig. 4, as set forth.

5. The combination of the sleeve G and the tips E and F, as and for the purpose described.
